| Re: 150R High Comp Piston
Your the man if you can improve on that piston. .035 from deck. valves .050 and .045 from piston. 13:1 The valves take up 75 percent of the chamber so sinking them would really hurt compression. Unshrouding, yes. But there goes quite a bit of compression. This motor should not be compared to the norm though. I haven't fully figured it out myself, I have flow numbers saying that the engine should make almost 30 hp but it doesn't. HP per cc this thing stomps 450s though. |
